TENEBRIONID^. 17^ 



Widely spread ia Europe under the bark and in the worm-eaten 

 parts of dead or decaying oak-? ; a single specimen was taken in June 

 1876 by Mr. O. E. Janson under a decaying boletus {Poli/poras 

 sqiutmosus) which he had placed as a trap for coleoptera in the hollow 

 trunk of a partially decayed oak in a hedgerow in a field at Crouch 

 End, Hornsey. 



The species, as Mr. Janson when introducing it as British remarks 

 (Ent. Record, xv. 1903, 128) bears a general resemblance to some of 

 the Anisotomides and especially to Agaricojjhagus cephalotes. If properly 

 searched for the insect will probably be found again, and may be 

 overlooked owing to the fact that old decayed oaks in fields are very 

 unproductive of beetles and are usually passed over by collectors. 



PALORUS, Duval. 

 There has been considei-able confusion in our lists with regard to 

 the genus Pcdorus, Duv. {H)jpo})hloeus auct. 2)asslm) : the species which 

 has stood in the British collections as HyjMjMoeus dejyressus, Fabi%, is 

 not the Fabrician insect and must be referred to P. ratzehurgi, Wissm. 

 { — ambigaus, WoU.) and we must also add another species, P. suhde- 

 pressus, VVoll. ( = bifoveolatus, Baudi) ; the true P. dep-essas, F., does not 

 appear as yet to have been found in Britain, although it probably 

 will be. Mr. Champion .(Ent. Mo. Mag. xxxii. (2 Ser. vii.) 189G, 27) 

 gives an excellent account of the distinctions between the three 

 species, which we here quote : 



I. Autennary orbits (or sides of the 

 front) moderately prominent, not 

 extending backwards so as to hide 

 the anterior margin of the eyes 

 as seen from above. 

 i. The antennary orbits separated 



from the epistoma (or clypeus) by 



a distinct furrow ; head (the 



episterna excepted) and pro- 



thox'ax coarsely, closely punctate, 



the punctures on the prothorax 



becoming vei-y coarse and dense 



towards the sides ; prothorax 



much broader than long; elytra 



coai'sely punctate - striate, with 



one or more of the inner 



interstices irregularly biseriate- 



punctate and the others uni- 



seriate-punctate . . . .P. depressus, Fah: (1790). 



ii. The antennary orbits not separ- 

 ated from the epistoma by a 



{=uaicolor, Oliv. (1790).)
